+Subject: [PATCH] input: goodix: Include I2C details in names for the devices
+
+libinput uses the input device name alone. If you have two
+identical input devices, then there is no way to differentiate
+between them, and in the case of touchscreens that means no
+way to associate them with the appropriate display device.
+
+Add the I2C bus and address to the start of the input device
+name so that the name is always unique within the system.
